ABHD17C‐Mediated S‐Depalmitoylation of BCL6B Enhances CD24 Transcription to Resist Macrophage Phagocytosis in Pancreatic Cancer

Advanced Science, EarlyView.
ABHD17C‐mediated depalmitoylation of BCL6B at Cys442 blocks its nuclear import and triggers ubiquitin‐dependent degradation, attenuating transcriptional repression of the anti‐phagocytic signal CD24. This mechanism enables pancreatic cancer cells to evade macrophage phagocytosis and fosters an immunosuppressive microenvironment.

Chloroquine triggers Epstein-Barr virus replication through phosphorylation of KAP1/TRIM28 in Burkitt lymphoma cells. [PDF]

PLoS Pathogens, 2017
Trials to reintroduce chloroquine into regions of Africa where P. falciparum has regained susceptibility to chloroquine are underway. However, there are long-standing concerns about whether chloroquine increases lytic-replication of Epstein-Barr virus ...

Herba Lysimachiae Polysaccharide‐Modified Selenium Nanoparticles Alleviate Oxidative Injury in Kidney Stones via TOMM22‐Regulated Mitophagy Activation

Advanced Science, EarlyView.
HLP‐SeNPs, a Lysimachia christinae polysaccharide‐modified selenium nanoparticle, treat kidney stones by downregulating TOMM22 expression, which reduces PINK1 translocation into mitochondria and promotes its retention on the outer mitochondrial membrane.

IKKβ and USP28 Regulate HEY1 Stability to Promote Cancer Stemness and Immune Evasion in Hepatocellular Carcinoma

Advanced Science, EarlyView.
The uncovered IKKβ‐USP28‐HEY1 axis fuels cancer stemness and immune evasion in hepatocellular carcinoma. USP28 deubiquitinates HEY1 upon IKKβ‐mediated phosphorylation, conferring PD‐1/PD‐L1 blockade resistance. Pharmacological inhibition of USP28 sensitizes resistant tumors to anti‐PD‐1 immunotherapy, revealing a promising therapeutic strategy ...

Synergistic Remodeling of Tumor Immune Microenvironment via a DNA Nanodevice Integrating STING Activation and Lysosome‐Targeted PD‐L1 Degradation

Advanced Science, EarlyView.
A rational design DNA nanoplatform not only achieves efficient PD‐L1 degradation but also triggers robust STING signaling. The nanodevice effectively reprograms “cold” tumors, leading to potent inhibition of tumor growth and metastasis in vivo. ABSTRACT The cGAS‐STING pathway is a cornerstone of innate antitumor immunity; however, its therapeutic ...

Isradipine – a calcium channel blocker – does not potentiate chloroquine antiplasmodial activity against Plasmodium falciparum

Parasite, 2005
Culturing fresh clinical isolates of P. falciparum and using the isotopic method, we tested separately chloroquine and isradipine – a calcium channel blocker –, and also the combination isradipine plus chloroquine.

Chloroquine inhibits Ca2+ permeable ion channels-mediated Ca2+ signaling in primary B lymphocytes

Cell & Bioscience, 2017
Background Chloroquine, a bitter tastant, inhibits Ca2+ signaling, resulting in suppression of B cell activation; however, the inhibitory mechanism remains unclear.
